Gimbal Calibration With IMU MPU-6050

Some gimbals are hard to calibrate because there is no way to graph the position in real time.

This instructable will show you how to graph the position of a 2 axis gimbal for tuning a PID. To achieve that I'm using a second IMU and an Arduino linked with Processing over serial.

Supplies:

Step 1: Materials

In my case, I'm using an EvvGC 1.3 open source gimbal controller. This controller doesn't have a position graph tool. I've tried to stream the angle data over serial, but this task is time-consuming for the gimbal controller and it's not a good way to tune the PID. So, you'll need a second IMU and an arduino to stream data in real time without consuming controller's resources.
